Cetasol - Maritime Sustainability

Cetasol helps maritime operators reduce fuel use and emissions by giving actionable, real-time guidance and analytics. It delivers this through AI-powered platforms—iHelm for eco-driving, predictive maintenance and crew training, and CetaFuel, a virtual fuel reader—deployed as a subscription SaaS. The technology combines AI, cloud services and digital-twin models to adapt to diesel, electric, and hybrid vessels without costly hardware changes. Cetasol targets fleet operators and maritime service providers and integrates into fleet operations to support regulatory compliance and operational efficiency. The company is based in Gothenburg and has secured fleet deals with large operators, illustrating commercial traction in short-sea and ferry markets.
